This invention relates to methods of preparin shingle material andforming shingles there rom and providing apparatus therefor. The generalobject 1s to provide a ma- 5 chine for cuttin the webs of shinglematerial into shingles any desirable shape. Special objects of theinvention will be apparent from a consideration of the drawing and thefollowing description thereof.

Of the drawing, Fig. 1 is an elevation of the machine for cutting theshingles; Fig. 2 is a sectional lan view of the shin 1e cuttin machineal dng the line 2-2 of ig. 1';

an Fig. 3 is an enlarged plan view of a por- 5 tion of a cutting rollerof'the machine.

As is well understood, ordinary asphalt shin les are made byimpregnating sheets of suita le material, such as felt, with asphalt orsome other suitable material, and, while the asphalt is soft, bysprinkling on the surface of the sheet suitable granulated mineral suchas slate. The sheet of prepared material is then dried until the asphalthardens sufficiently, and the'webs thus formed. are then ordinarilyrolled into rolls for transportation or other use. The websare thenpassed through suitable machines for cutting them into individual orstrip shingles. v The web is passed over a roller 31, under a roller 32,andover a roller 33. Around these rollers 31,32 and 33 plays a beltorbelts 38 against. which the web is pressed by the adjustable roller 32.These rollers are so positioned and arranged as to hold the websubstantially taut, and, together with the belt 38, to ull the web andto push it forward towar s the cuttin portion of the machine.

web forwardly, but it also supports the web so that danger of rupture ordistortion is eliminated.

This cutting portion comprises a framework 34 in which is journaled' acutting roll er 35. The up er surface of this roller is substantially oft e same elevation as the upper surface of the feeding roller 33, sothat the web 11 is fed horizontally across the top of the cuttingroller. mounted for vertical movement and is adapt- 50 ed to be sopositioned as to press down on the A second roller 36 is web 11, as itpasses over the'cutter roller, sufficiently to cause the knives 37mounted on the surface of thecutter roller to cut the web into shin les.

The kmves 37 mounted on the cutter roller 35 are arranged and shaped soas to cut out shingles of the form desired. After being cut, theshingles ,40 are passed out of the machine and removed in any suitablemanner. The cuttin mechanism may be' operated in an suitab e manner.

e roller 32 ismounted for vertical movement and may be elevated orlowered by means ofa hand wheel 41 or in any suitable manner. I preferto have the hand wheel connected to the bearing 42 of the roller bymeans of a worm wheel 43 which is threaded on to a shaft 44 connectedwith the hearing. If it is desired to remove the web, or when the web isentered into the machine, the roller 32 may be elevated and the web 11passed freely into the cutting rollers. The roller 36 may be elevatedand lowered m a similar manner by means of a hand wheel 45 which isarranged to operatethe worm wheel 46 threaded on to the shaft 47 whichis fixed to the bearing 48 of the roller 36.

As will be understood, when the shingles are cut from these webs ofpliable material, there is a tendency for the shingles to be carriedaround on the surface of the cutting roller 35 between the knives. Inorder to strip the shingles from the surface of this roller. anysuitable means may be provided. I prefer to providefor the purpose thewires or rods 50 which pass between the webs 11 and The belt 38 not on yassists in carrying the the surface of the roller 35, passing throughopenings 51 in the knives. and, preferably.

along grooves 51 in the surface of the roller.

These rods are supported in any suitable manner. I prefer to supportthem by their ends on each side of the cutting roller, and by means of anut 52 threaded on one end of each of the rods, the rods may besuificiently tightened for the purpose.

It is to be understood that these strippers will strip from the cuttingrollers not only the complete shingle but also any waste pieces that maybe cut out by the knives.

I claim as my invention:

1. In a shin le making machine, a cutting roller having nives providedwith cutting edges, means for stripping cut shingles from 5 said roller,said means comprising elongated members running across a portion of theperiphery of the roller, and means for tensioning said elongatedmembers, the cutting edges of the knives projecting beyond the peripheryof the roller a greater distance than the elongated members.

2. In a shin ie making machine, a cutting roller having nives providedwith cutting edges, means for stripping cut shingles from said roller,said means comprising elongated members running across the upper portionof the periphery of said roller,'said roller having circumferentialgrooves therein, and said elongated members running horizontally in saidgrooves, and means for tensioning said elongated members, the cuttingedges of the knives projecting beyond the periphery of the roller agreater distance than the elongated members.

3. In a shin 1e making machine, a cutting roller having ives providedwith cutting edges, means for stripping cut pieces of shingle materialfrom said roller, said means comprising rods running along the peripheryof 8 said roller, and means for tensioning said rods the cutting edgesof the knives projecting beyond the periphery of the roller a greaterdistance thansaid rods.

4. In a shin 1e making machine, a cutting 85 roller, a mova ly mountedendless belt for feeding strips of shingle material to said cuttingrc-iler, means for pressing said strips against said belt, worm and wormWheel means for adjusting said pressin means, and

means for stripping cut pieces of shingle mat-erial from said cuttingrollers,

5. In a shin 1e making machine, a cutting roller, a mova ly mountedendless belt for supporting and feeding shingle strips to said cuttinroller, adjustable means for pressing said s ingle strips against saidbelt and for deflecting the belt below its normal plane of travel toobtain a firmer grip on the material, and means for stripping cut piecesof shingle material from said cutting roiler.
